As already mentioned you can declare an unordered map of any type. Let's have a unordered map named first with string and integer type.
unordered_map<string, int> first; //declaration of the map
first["One"] = 1; // [] operator used to insert the value
first["Two"] = 2...
Suppose you are comparing value with some variable
if ( i == 2) //Bad-way
{
doSomething;
}
Now suppose you have mistaken == with =. Then it will take your sweet time to figure it out.
if( 2 == i) //Good-way
{
doSomething;
}
Then, if an equal sign is accidentally left out, the ...
In PHP, variable values have an associated "truthiness" so even non-boolean values will equate to true or false. This allows any variable to be used in a conditional block, e.g.
if ($var == true) { /* explicit version */ }
if ($var) { /* $var == true is implicit */ }
Here are some fun...
Suppose you are creating a function that requires no arguments when it is called and you are faced with the dilemma of how you should define the parameter list in the function prototype and the function definition.

Alternatively, you can use the uninstall command, which does exactly the same thing:
$ rbenv uninstall 2.1.0
If this version ha...

val a = arrayOfNulls<Int>(3) // creates an Array<Int?> of [null, null, null]
The returned array will always have a nullable type. Arrays of non-nullable items can't be created uninitialized.
General-purpose stopwatch for timing how long a function takes to run:

As mentioned here, the old-school method to run another script is by using temporary files. Simple echo it into a file and then run it(and remove it optionally).
Here's the basic concept:
@echo off
echo //A JS Comment > TempJS.js
echo //Add your code>>TempJS.js
cscript //nologo //e...
